Measuring Sound Speed with Arduino
Abstract: Arduino is an open-source electronic prototyping platform. With Arduino and the corresponding sensors, we can design experimental devices for scientific inquiry. This article introduces the application of Arduino and sound sensors in sound speed measurement experiments, using the design, production, and operation of a sound speed measurement device as an example, providing ideas for our own hands-on experimental device design for scientific exploration.
Keywords: Arduino, sound speed measurement, sound sensor, scientific inquiry

8 Fun and Easy Arduino Projects to Try
Source: Circuit City
Editor: strongerHuang
Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It is very easy for beginners to master while providing enough flexibility. Arduino is not only the most popular open-source hardware globally but also an excellent hardware development platform and a trend in hardware development. With Arduino, we can easily create many interesting electronic designs. Here are 8 open-source projects from Circuit City for you to try
Implementing printf Function from Scratch Based on Cortex-A9 UART
Here is a collection of articles on the ARM series:
"Learning ARM from Scratch Collection"
0. Introduction
The UART is a very important module in an embedded system, serving as a bridge for interaction between the CPU and the user. User input to the program and CPU output to the terminal both rely on UART.
This article will explain the principles of UART and how to write a driver program based on the UART controller of Exynos4412.
1. What is UART
UART stands for Universal Asynchronous
Simulation of Communication Systems Based on Software Defined Radio Using Simulink
This course includes introductory knowledge of analog and digital communication systems, aimed at undergraduate students majoring in electrical and computer engineering.
This package contains course materials for an introductory analog and digital communications systems course taught to undergraduate electrical and computer engineering students.
An integral part of the course design is a series of laboratory modules through which students explore course topics using low-cost SDR hardware (e.g., RTL-SDR or ADALM-PLUTO) and MATLAB/Simulink software tools.
Using these laboratory exercises, students implement various communication systems
Three Steps to Challenge X86 and ARM Chips by Loongson
In the fierce competition of the global chip market, X86 and ARM architectures have always dominated. However, in recent years, a Chinese independent CPU manufacturer, Loongson, has been challenging these two traditional giants with its unique strategy and firm determination. Loongson's goal is not only to occupy a place in the domestic market but also to establish an independent ecosystem alongside X86 and ARM on a global scale. So, how does Loongson plan this grand blueprint? What specific content does
How to Keep Your Android App Running Continuously
How to keep your app running continuously?
By default, if no cross-process deployment configuration is made, each Android app runs in a separate virtual machine, with each virtual machine corresponding to a process. When the app is reclaimed by the system or actively killed by the user (through app management software), the process exits completely.
In some scenarios, when the app's process exits, we still want to perform some operations. For example, after

Understanding ARM Cortex-M4 and Cortex-M0+ Interrupt Priority and Nested Preemption Issues
Sitting on the high-speed train from Shanghai to Beijing, the long journey really makes one feel bored (I couldn't get a direct train, so I can only go slowly, stopping at every station. It's ridiculous that in the high-speed train era, it still is like this. It reminds me of the time in college when I took a green train home
